how to "disable" a engine?

The chapter "13.7.5.17 SHOW ENGINES Syntax" says there is a "support" column value "disabled",and "A value of DISABLED occurs either because the server was started with an option that disables the engine".
BUT when I disable the archive engine by adding "disabled_storage_engines="ARCHIVE"" in my config file,the "support" column value of engine archive is still "YES",not "DISABLED".
Is this a bug in mysql 5.7?

mysql> show variables like '%disabled%';
+--------------------------+---------+
| Variable_name | Value |
+--------------------------+---------+
| disabled_storage_engines | ARCHIVE |
+--------------------------+---------+
1 row in set, 1 warning (0.00 sec)
mysql> select support from information_schema.engines where engine='ARCHIVE';
+---------+
| support |
+---------+
| YES |
+---------+
1 row in set (0.02 sec)
